They certainly help but not all trucks have them, at that point you’re dealing with 3 different mirrors on each side between the fisheye, regular, and separate overhead mirror, and there are still little spots that are hard to keep an eye on. Stack that on top of drivers doing the same monotonous task for 10+ hours a day and you’re really better off just staying out of their blind spots as best you can
Is’t there an overhead mirror for that blind spot?
